Product Description:

The 8I64T400400.00x-1 belongs to the 8I6 ACOPOS Inverters series from B & R Automation. It is an inverter and I/O module intended to supply regulated motor power while also collecting high-speed position feedback and discrete control signals inside a centralized motion system. By combining power electronics with counter, relay, and logic interfaces, the unit streamlines cabinet layouts in automated machinery that requires synchronized axis control and low-voltage field wiring.

This model delivers a rated output of 4 kW, allowing it to drive medium-power servo or induction motors. The integrated primary counter accepts incremental encoder signals up to 100 kHz, and a secondary A/B counter channel operates at 20 kHz when differential quadrature feedback is used. Both counters store positional data in a 32-bit register, providing a wide numeric range before rollover occurs. Digital inputs have an impedance of 12.1 kΩ, so PLC sourcing cards experience only minimal current draw. Sampling takes place every 4 ms, aligning I/O updates with the inverter’s internal control loop. The housing is 184 mm high, 142 mm wide, and 158 mm deep, allowing it to fit in standard 200 mm cabinet frames without obstruction.

The module weighs 2.35 kg, which eases DIN rail installation and keeps vibration loads low on adjacent devices. Its DO1 transistor can switch discrete loads at up to 100 Hz, and leakage current is limited to 3 µA when the transistor is off, helping protect sensitive sensors. The onboard relay R2 handles resistive loads up to 2 A, with a mechanical life expectancy of 100,000 operations and a minimum load of 10 mA at 5 V DC. The X2x system bus draws only 1.6 W, keeping control-level power demand low.
